To all whom it may concern auroararic MACHINE;

messes.

Be it, known that I, TILL-1AM oflllinois, have invented certain new and useful Improvements in Automatic Machines, of which theiollowmg 1s a SPQClfiCfltion. 7. r 1

Inthe manufacture of; small articles of metal which fundergo successive operations it is desirable so far as iossible to reduce" the number of operatives by. making the machines automatic in their operation, eX-

1 tending such automatic features not only to the feeding of the material thereto and the stacking of the articles coming from the machine, but also to the stopping of the machine in case of accident,

It is the object of thepresent invention to provide in a machine for working sheet metal articles, such for instance as can tops or the'like, automatic mechanism simple in construction and eliicient in operation where.

by a single operative-can attend to a number ofmachines, the feeding of the material to the machine and the stacking of the product as it comes from the machine being entirely automatic, and also provision being made whereby upon any interruption of the machines action. suchas that caused by the jamming of articles therein, the machine will be immediately brought to a standstill.

, In order that the invention may be rea dily understood a preferred embodimentjof the same is set'forth 1n the accompan m g drawings and in the description based thereon. Y

Obviously the invention is susceptible of embodiment in varied constructional forms other than that shown, wherefore the drawing and description are to be taken in an illustrative and not in an unnecessarily limiting sense.

In the drawings-Figure 1 is a front elevation of a machine for acting upon can tops and embodying the present invention; Fig. 2 is a side elevation of the same machine; Fig. 3 vertical section on the line 3-3 of Fig. 1; Fig. 4 is an enlarged detail section on the line 4-.-i oii Fig. 1; Fig. 5 is a transverse section on the line 55 of Fig. i; Fig. 6 detail view of the clutch operating mechanism; Fig. 7 is a transverse the automatic stacking mechanism taken: on

the line 88 of ig." -12; F 9 is a similar view taken on the line 99 of Fig. 12; Fig. 10 is a topplan view on the line 10-10'of 9; F ig. 11 isa bottom plan view on the line 11-l1 of Fig. 9; Fig.12 is a section on the line;12 l2 of Fig. 9; and Fig. 13 is a sectional detail view on the line 13 13 of Fig.12f i As illustrated the machine includes the frame 21 uponwhich the inclinedstandards 22 are supported having journale'd in their upper portions the drive shaft eccentri .cally connected to the reciprocating member 24 guided in its lower portion by means of the cooperating guide members 25-26 and carrying a sultable dlefor acting upon the articles, all ofwhich arrangement is .old and wellknown. Theshaft 23 1s sultably driven bymeans of. the fly wheel 27 connected to said shaft by a clutch of the well known half round pin and socket type. The. l

complementary surfaces 28 and 2-9 of the fly wheel and shaft respectively being each provided with one-half of a .circular'recess or socket and the former having journaled therein a half round pin 30, to which is attached a dog 31 under the control of the spring 32 which tends to rotatethe pin.30

in such manner as to form an interlocking and shaft.

Mounted upon the bracket 33 at the side of the machine is an angle lever 34 one arm 35 of which is adapted to engage a notch of the dog 31 whereby to hold the same against driving connection between the: fly wheel the tension of the spring 32 with the pin 30 v out of interlocking engagement with the shaft. The other arm of the angle lever is pivoted at 36 to a link rod 37 which is connected at its lower end to a pedal 38 downwardly pressed under the influence of the spring 39. Acatch 40 is pivoted to the bracket 33 by a pin 4E1 and extending through said bracket and having fixed upon the opposite side thereof an arm 12, which is connected by means of the link rod 43 with a lever 44: fixed to a rock shaft 45 journaled in the machine frame and overbalanced or counterweighted at its outer end. I

In case the operator desires to throwin'the clutch and efiect the driving of the machine from the fly wheel 27 he presses upon the pedal 38 and thereby releases the dog 3lcand permitsthe spring 32 to efi'ect the coupling of the parts. If the foot he thenrem'oved fromthe pedal the dog; 31 would make one handle earths catch 4-0 will release for the stopping of the v acciucn'tor interruption in the passage of rcvolution around the shaft with the ii) wheel and would be arrested by the arm 35 of the angle lever throwing out the clutch, if it were not for the counterweighting of the lever -5- outer end of the which causes L136 same to drop liftingthe arm-l2. and causing the catch it to engage the pm ll) of the arm in en a ement with holding the latter reafter lifting the lever the dog 31 By the L6 andpermitare arm '35 to en age the dog illunder the action of thespring 35).

The'automatically acting means pr vidcd machine in case of material to the machine will'nmv'be described. A chute =17-leads from the auto- "maticfeeding mechanism, to be hereafter described, through thema chine to the automatiostacking 111eans,hereafter to be described. T his chute, along which the articles travel by gravity as they leave the die, is

providedat a point adjacent the die'with a stroke of the machine. The finger 50 has a shoulder 51thereon and between said shoulder and the lower edge of'the bracket the finger. is enveloped by a compression spring 52-ivhich normally holds the finger yieldingly extended. The upper portion of the finger within its bearing'in the bracket a9 is notched at 53 to provide a cam face. A latch 54 is pivoted at 55 to swing from the bracket 49 and carries a pin 56 which normally lies within the notch 53 above the cam face. The rock shaft $5, to which is securedthe handle l i of the clutch operating mechanisnn has also secured thereto an arm 57 which projects beneath the bracket l9 adjacent the normal path of the'latch 54. In the regular operation of the ;machine the pin 50 will move freely with the reciprocating member 24, but if, for any reason the articles become jammed within the chute 4-7 so as to obstructthe aperture 48 the finger 50 striking one of the articles will be arrested compressing the spring 52 and cansing the cam face at 53 to act upon the pin 56 throwing the latch to the right (Fig 3) whereupon the notch 58 on the lower end of the latch will strike the arm57 rocking the shaft 45am], thereby releasing the pin 46 0f the arm 35 from the catch 40 and permitting the said arm 35 to engage the dog 31 and throw out the clutch stopping the machine. 1

Provision is made for feeding the articles individually to the machines in the manner following! At the entrance to the the pin chute l7 above the die is arranged a feed magazine 59, uprights 60 being employed to form the walls of the magazine for the retention of a vertical stack of the articles. lVithin the lower portion of the magazine are arranged in superposed relation a pair of upper feed plates 61 and a pair of lower feed plates 62 the members of each pair mounted for reciprocation toward and from each other and the reciprocating movement of the two pairs being in alternation so that the lowermost article of the stack will be dropped upon the lower feed plates and the upper feed plates will approach each other so as to support the stack while the lower J feed plates withdraw and permit the article held thereby to drop in the chute in a well 'lmown manner.

reciprocating movement vertically disposed To effectthis alternating rocker beams 63, are mounted at the two sides of the magazine upon shafts 6%, (ll. The lower end of'each rocker beam is connected by a link 65 with a stud 66 carried by one of the members 62 of the lower pair of feed plates while the upper end of each rocker beam is connected bya link (57 with a stud 68 carried by one of the members 61 of the upper pair of feed plates. The two rocker beams 64. are cross-connected by means of a link 69 extending diagonally be tween the arms 70 and 71 forming infeifect downward and upward extensions respectively of the rocker beams 63, said extensions being here shown as separate arms 70 and 71 fixed upon the rocker beam shafts (34-. The extreme end of the arm 71 is connected by means of a link 72 with thereciprocating member 24- at-73. It will be obvious that as the member 24: reciprocates the rocker beams will operate in unison so as to cause the members of the lower pair of feed plates to approach each other as the members of the upper pair of plates recede from each other and vice versa whereby to obtain the feeding of the articles one by one from the magazine to the chute.

At the lower end of the machine is mounted upon the frame 7% the magazine for the finished articles and comprising uprights 7 5, which form the walls of the same, and a base 76. The latter is beveled at one side to form an inclined approach at 77 by means of which a space is provided beneath the rear edge of the lowermost article forming the stack within the magazine so as to facilitate the introduction of the next article beneath the stack. lf'he outer edge of the inclined approach 77 is flush with the upper face of a table 78 upon which the articles drop as they leave the chute 4E7. This table has formed therein a longitudinal groove or guideway 79 within which is mounted for reciprocating movement a plunger 80 which held within the glide groove by the plates 81 overlying the base of the plunger. This The plunger is withdrawn after each forv ward movement by "means of a toggle connection including the members and 86 and the'arm 87 on the rock shaft 88, the said shaft being connected by means of the arm 89 and the link rod 90 eccentrically to the shaft 23 at 91. The toggle member 86 projects beyond its pivotal connection at 92 with the member 85 as indicated and is provided with terminal pin 93 which engages the under side of the toggle member 84 so as to prevent the members 8% and 85 assum ing a straight position thus guardingagainst damage to the mechanism, in case the action of the plunger 80 is obstructed, by the breaking of the toggle at 92;

In order toinsure thedelivery of the arti cles one at a time from the chute to the table in front of the plunger a lock mechanism is provided which comprises a gate bar 94: having upon its two ends fingers 95, 96, said bar being mounted to tilt upon a fulcrum 97 by means of ears 98. One of these'ears extends below the fulcrum point and is forked to take over a pin 99 carried by an ear 100 upstanding from a rocking bar 101. pivoted at 102 and having at its opposite ends downturned portions 103, 104, spaced apart a distance corresponding substantially to the stroke of the plunger. The plunger is pro- .vided with a stud or roller which eX- tends toward the rocking bar into position to engage the downturned ends 103 and 10 at the limits of its working and return strokes. 7 T

It will be seen that as shown in Fig. 9the lock mechanism has its parts so positioned as to receive and arrest an article descending the chute, the'previous article resting upon the table in front of the plunger. As

.the plunger moves forwardand shoves the roller 105 will. lift the end 103 causing the rocking bar to move 111 the opposite direction retracting the finger 95 and liftin the finger 96 to permit the next article toenter the lock, this operation being repeateda's the articles are fed from the machine, 'dehvclutc 1 to stop the machine.
